The program also houses the Beckwith-Wiedemann syndrome (BWS)/isolated hemihypertophy team, a sub-group within the Hereditary Cancer Predisposition Program that works with families of children with BWS and isolated hemihypertrophy, diseases that genetically predispose children to cancer.

The Pediatric Hereditary Cancer Predisposition Program at The Children's Hospital of Philadelphia uses the latest advances in oncology and genetics to provide care and counseling to children with genetic predisposition to cancer.

Hereditary factors that promote organismal survival and reproduction in a particular environment tend to be precisely those that proliferate across the generations and thereby come to characterize natural populations.
